Much -1- already about school issues. Every country has its own particular issues, but still we have much in common. Children -2- in large classes that results in many of them fall behind. Home assignment -3- properly and very often -4- by a teacher either. Last year some of these issues -5- during the teacher conference which -6- on March 31^st. Some rational solutions -7- but as far as I am concerned they -8- yet. The pupils -9- usually for being inattentive and the teachers -10- for being too strict. Neither of approaches can be considered as productive as they give no positive results. The exams -11- every year. The results of the exams -12- regularly for the last five years. The grades -13- carefully for all these years and the conclusions that recently -14- are not the most favorable ones. For example when the students -15- 5 years ago their grades were 15% higher that the grades of the same exams nowadays.
